    i discovered something pretty funny about the way mahle graphs rider power on their ride portal. when the value is zero, e.g. if you...

    your assumption about where peak torque occurs is incorrect. it occurs at much lower rotational speeds and is in fact in the 27nm range...

    heheh more like : “heyyyy is there any way we can claim more torque than a competing mid-drive?” “yeah let’s just pretend all bikes...

    … also, it’s pretty easy to know how much torque the motor is really supplying if we trust the power output values given by the mahle...

    i think a lot of people are in agreement that this is pretty shady on mahle’s part - while there is some truth to the fact that the vast...

    i believe it just supplies more current. they must have discovered after a few years that the system could take it. or maybe the...

    i was surprised to see a while back that the "new" version of the mahle x20 was being rolled out to older bikes - everything but the UDH...

    here’s a thought - since efficiency varies from 75 to 90 over the full cadence range, and the data is we’re gathering is electrical...

    since we can only easily measure electrical power, you can basically disregard efficiency. the only effect of the change in efficiency...

    by comparison and for giggles.... this is the hill we live on - behind the tallest building on the left; our views are all in the...

    i think three minutes of data would be enough per run, so if we assume the last run is 120 human watts and 240 motor watts, total weight...

    yes - it averages 3.6 times the other speed value which is kph. before my latest health troubles i could maintain 200w for a very long...

    i'd find a hill of around 5%, ideally at least 300' of climb, no stops, keep cadence around 80, heart rate at a steady sustainable value...

    Fair enough. I'll resist the urge to throw up my hands till I have a few FIT files under my belt. But first, I should design some...

    it's interesting that the .fit file contains headers for almost every cycling parameter you could imagine, including "ebike_assist_mode"...
